I then tried disabling the flash uploader, and I get the following error "The uploaded file is too large for the server to process". I get this error when trying to upload an avatar to the server (gravatar works)

When I try to import a new language, once it's uploaded, it throws a HTTP error 500 Internal Server Error.

I've checked the data and internal_data folders and they are both in 777. There are files within the attachment folder form the import. Not sure what I can do. Is this a bug?
